Dual-Port 10/100/1000BASE-T TOE PCI Express® Ethernet Controller
The BCM5709C provides a dual-port, fully integrated Layer 4 and Layer 5 solution - TCP/IP, RDMA, and iSCSI along with two complete 10/100/1000BASE-T Gigabit Ethernet Physical Layer Devices, IEEE 802.3 compliant Media Access Controls (MAC) and Physical Layer Transceiver solution for high performance network applications. By itself, the BCM5709C provides a complete dual-port, single-chip Gigabit Ethernet NIC with TCP/IP Processing Engine, RDMA NIC (RNIC), iSCSI HBA or LOM solution.
The BCM5709C is different from other network controllers because it can process the TCP/IP and relevant L5 protocols on data directly from the application buffers on the host, thereby relieving the host CPU from these time-consuming operations. On the receive path, the BCM5709C processes the frame up to the highest layer supported present in it, for example, the BCM5709C processes the frame for RDMA when the frame is an RDMA frame.
- Dual-port, single-chip solution for LAN on Motherboard (LOM) and Network Interface Card (NIC) applications with integrated 10BASE-T/100BASE-TX/1000BASE-T transceivers in addition to PCI Express V2.0-Ready and PCI Express® x4 host interfaces
- Full Fast-path TCP processing engine supporting IPv4 and IPv6
- Industry's first dual-port 10/100/1000 TOE solution -power and space optimized for server blade and low-profile NIC applications.
- Extremely low CPU utilization for TCP/IP applications -freeing the host CPU to run application code
